Optiplex GX 240, 260, 270, 280 350w Power Supplies

I have currently looking for a replacement power supply in the 350W range for the GX 240,260,270,and 280 models. I have having a hard time finding a power supply without the rocker switch that will fit these systems. Does anyone know where I can find such power supplies and are these systems in the "non-standard" power supply category? If so, will I need to track down adapters for each model or are they similar enough to all use the same adapter ?

Hmm...sounds like I could end up with a problem then. According to Dell Tech Support the 350w power supply (part # c4849) will work in all four models so long as they are all the mid-tower chassis (which they are).

Ask the Dell Tech How does a 24 pin connector fit onto a 20 pin ATX? There is techmically a way to shoehorn it in there but its definitely Not the same on all. Some are 24 pin and Some are 20. An interesting Idea that theres one supply to fit all. Even more interesting if its REALLY 305w and not 250 or 220 or 200 watts. The Documentation for the GX280 Verifies this. They must aLL Be towers to interchange power supply parts as far as the CASE of the supply goes. The connectors and wire length?? thats a whole nuther issue. There may be a specifc version of GX280 tower motherboard that fits the SKYDIVE Mini Tower case. Perhaps they mean NEO instead of MR SMITH.

This is Mr SMith This is NEO The NEO has always been referred to me as the SKYDIVE CHASSIS.

i was told atx12v was the correct size..with a little modification ive heard that to get it to fit you need to hack a hole into the back of the case. while i have no problem doing this can someone whos done it already tell me if its a big hole? small hole? and what do i use to CUT it. if thats wrong if something fits better can someone please steer me in the right direction. need it in the 450-500w range.

If the spec is correct it should work fine. However Im not sure I trust a 480w psu thats only $20.

Only Tower case can use REAL PSU. Other cases its an itty bitty box and doesnt fit.

On the Left the HackJob on the Right the original.

Hackjob by speedstep using right angle tin snips 45 seconds.

Using Kronus Nibbler tool .. 15 minutes.

Generally I use the tin snips now as I dont care if anyone thinks its an ugly hole.
